vTO 'ALL WHM IT MAY CQNCERN:

Be it known that I, J. KENNEDY MAX, of Springfield, Hampden county, Commonwealth of Massachusetts, have invented a new and useful improved Moulding Machine for Book-Backs and I do hereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanying dra'wngs, andV to the letters of reference marked thereon. In the vdrawings-- Figure 1 represents avperspeotijve View of my invention.; and

Figure 2, a plan View of the same'. p Y y y This invention consists of amechanical device for moulding the curve of the back, in the binding of books, and forming it ofthe proper size. 'l

My invention consists of'a device for moulding the backs of books, giving them the prop'er curve and'size.

` In` construction, I form my machine of a table, A, to which a press is attached in the following manner: On cach side of the table, at the top, is placed a slidingudevice, consisting of the slides B Bworlzing in the guides VC C C C. Through these slides, crossing 'the-top of: the tableat a suitable distance above it, is passed a cylinder, D; various sizes of cylinders can be used here, the holes in the slides `B B, through ,which the. cylinder passes, being made adjustable by means of the slotted pieces a a. On the top ofl the table-'is placed a slidingbed, E, which-has various-sized grooves, c c'c, sunk in it. These groovesare made parallel to the-cylinder '1), which is -meant to be pressed down in any one of them,formling'the curve of the black between, and forming it of the size which that cylinder and groove determine. At the lower end of each. of the slides B B is attached a rod, F F, `which rods pass through guides G G fastened to the frame ofthe table. Thevrods are attached at their other ends to the bar4 H, which is Worked vertically by the treadle I, Between the guides Gr Gr and the lower ends of the slides 13B, coiled around the rods F F, are spiral Vsprings K K, which thronY the' slides with the cylinder up again, after they have been pressed down by the treadleLand the `pressure has been relieved. Steam is passed through th'e cylinder D 'for'the purpose of heating it, so-as to form the mould more perfectly, lWhen this, by reason of the situation of the machine or the absence of steam, is impossible, the cylinder can be heated by means of ir-on rods, which are heated and put into it. One of these' rods is' shownin the iig. 1,

marked X. l l

This device forms avery neat and convenient press for the purpose described, andl is especially useful in the easy manner by which different sizes of moulds may be used Without much diiculty in rearranging the press; all that is required being. to. shift the bed E, and sometimes to change the cylinder D. The arrange-l ment of the spring treadle in throwing the cylinder up, after a pressure is made, also adds` greatly to its completeness. l l l 4 Now, having described my invention, what I .claim as new, and desire to secure by Letters Patent, i s-,

1. The adjustable cylinder D, constructed.substantially as and fortbepurpose specified. 2. The use of steam or the heated rods X, for the purpose of heating the same, substantially as described.

3. The adjustable bedE, operating substantiallyas described.

4. The combination of the cylinder D, bed E, slides B B, and treadle I, having the rods F Inland springs K K, with the table A, operating substantially as and for the purpose set forth. u

JOHN KENNEDY MAX.
